<p>The present invention discloses a wheelchair access system (10) with a folding platform (22) for use in conjunction with a vehicle having a floor. This access system includes right-side and left-side vertical arms (20) and an actuator powerable for moving same between positions both inboard and outboard the vehicle. A first platform section (26) is coupled to both the vertical arms (20) for movement by the actuator. A second platform section (24) is moveable between folded and unfolded positions with respect to the first platform section (26) as the actuator moves the right-side and left-side vertical arms (20) between positions inboard and outboard the vehicle, respectively. The access system (10) also includes a gear assembly for coupling the first platform section (26) to the second. Advantageously, the gear assembly pivotably moves the second platform section (24) in a controlled operation with respect to the first platform section (26). A flexible linkage (40) connected to the second platform section (24) provides for movement with the actuator.</p> |
